Item 4. Purpose of Transaction.

The Reporting Persons originally acquired the Common Stock reported herein for investment purposes. Consistent with such purpose, the Reporting Persons have had, and may have in the future, discussions with management of the Company and may make suggestions concerning the Company’s operations, prospects, business and financial strategies, assets and liabilities, business and financing alternatives and such other matters as the Reporting Persons may deem relevant to their investments in the Common Stock and other securities of the Company. Each Reporting Person expects that it will, from time to time, review its investment position in the Company and may, depending on market and other conditions, increase or decrease its investment position in the Common Stock or other securities of the Company.

Whether the Reporting Persons purchase any additional shares of Common Stock or other securities of the Company or dispose of any shares of Common Stock or other securities of the Company, and the amount and timing of any such transactions, will depend upon the Reporting Persons' individual continuing assessments of pertinent factors, including the availability of the Common Stock or other securities of the Company for purchase at particular price levels, the Company’s and the particular Reporting Person's business and prospects, other business investment opportunities available to the particular Reporting Person, economic conditions, stock market conditions, money market conditions, the attitudes and actions of the Board of Directors and management of the Company, the availability and nature of opportunities to dispose of the particular Reporting Person's interest in the Company, to realize trading profits or minimize trading losses, and other plans and requirements of the particular Reporting Person. Depending upon its individual assessments of these factors from time to time, each Reporting Person may change its present intentions as stated above, including determining to acquire additional shares of Common Stock or other securities of the Company (by means of open market or privately negotiated purchases) or to dispose of some or all of the shares of Common Stock or other securities of the Company held by or under the control of such Reporting Person. In addition, each Reporting Person may from time to time enter into equity swap or other derivative transactions with respect to its investment in the Common Stock or other securities of the Company.

Except as set forth in this Item 4, the Reporting Persons have no present plans or proposals that relate to or that would result in any of the actions specified in clauses (a) through (j) of Item 4 of Schedule 13D of the Act.
